Calculate Median Array – Standard Method For this problem, we first taken the inputs. The inputs are the number of elements or the size of array and the data values which are to be stored in the array (a). One important thing to be kept in mind is that the data values are to be...
Previously Collection.sort copied the elements of the list to sort into an array, sorted that array, then updated list, in place, with those elements in the array, and the default method List.sort deferred to Collection.sort. This was a non-optimal arrangement....
